Steven had the worst customer service ever! Definitely needs a refresher in customer service. Reached out to corporate and spoke with Dutch to file a formal complaint. He was pleasant to speak with and was offered a burger. Will be back to redeem. Hopefully it will be a better experience to revise.

Not too much to say. Drive thru was pretty simple. Bought a strawberry slush. It was great as always.

The food was great and the car hop service is something I thought was a thing of the past. I was thoroughly pleased and will go back
